Ariana Madix was born in Melbourne, Fla. in 1985, and she has a younger brother, Jeremy, who was born in 1992. She went to Flagler College, where she received a Bachelor's degree in Theatre and Broadcast Communications, per her own website. She then moved to New York City and embedded herself in the sketch comedy world. In addition to that, she rode horses competitively, as fans have seen on Vanderpump Rules.

Ariana then moved to Los Angeles, where she is still based, and she has acting credits in projects like, Working It Out, Attack of the 50 Foot Cheerleader, Dirty Dealing 3D, and Dead End, in addition to shows such as NFL Writers Room, Single Siblings, AwesomenessTV, Dads, Anger Management, Lonely and Horny, and Waking Up With Strangers, per her IMDb profile

But she really rose to fame through Vanderpump Rules, where she is known as the snarky and smart member of the group. On the show, Ariana came out as bisexual, which she says doesn't bother her boyfriend Tom Sandoval, as it shouldn't. After coming out, she said she feels like she's living more "truthfully" now that fans now the real deal. They likely already assumed this, as a season before, Ariana famously hooked up with fellow cast member Lala Kent in the backseat of a car while Sandoval was driving, according to Bravo's The Daily Dish
